Buyers of innovative mountain bikes and high-end racing bikes expect the components to deliver maximum functionality at the lowest weight possible, along with maximum durability. In order to fulfill these expectations and maintain a high level of competitiveness, reliable and precise testing during development is essential. SRAM uses anHC 25 servohydraulic testing machine from ZwickRoell to perform fatigue testing on chains, cranks, and switching elements at their facility in Schweinfurt, Germany.
The HC series testing machine is designed for forces up to 25 kN and allows the operator to perform standard fatigue testing as well as flexure and component testing. This space-saving testing system uses an integrated hydraulic power pack, which is distinguished by an exceptionally low noise level, making it ideal for experimental inspections of the strength of newly developed components in the lab. The hard-chromed T-slotted platform and columns, as well as a wide range of accessories, make testing under special conditions a breeze—and testXpert R, the respective software solution, makes operation easier and supports the user optimally during each step.
SRAM uses the testing machine for product development, meaning calculation models and limit conditions are checked by the testing machine. Also, standard tests on components (e.g. to ISO 4210-8 §4.6) are performed with the machine, which are required as evidence of conformity in some countries.
